.SH SYNOPSIS
.sp
ibping [options] <dest lid | guid>
.SH DESCRIPTION
.sp
ibping uses vendor mads to validate connectivity between IB nodes.
On exit, (IP) ping like output is show. ibping is run as client/server.
Default is to run as client. Note also that a default ping server is
implemented within the kernel.
.SH OPTIONS
.sp
\fB\-c, \-\-count\fP
stop after count packets
.sp
\fB\-f, \-\-flood\fP
flood destination: send packets back to back without delay
.sp
\fB\-o, \-\-oui\fP
use specified OUI number to multiplex vendor mads
.sp
\fB\-S, \-\-Server\fP
start in server mode (do not return)
.sp
\fB\-\-dgid <gid>\fP
destination GID: use when GRH is required in packets (IPv6 format)
.SS Addressing Flags
.\" Define the common option -L
.
.sp
\fB\-L, \-\-Lid\fP   The address specified is a LID
.\" Define the common option -G
.
.sp
\fB\-G, \-\-Guid\fP     The address specified is a Port GUID
.\" Define the common option -s
.
.sp
\fB\-s, \-\-sm_port <smlid>\fP     use \(aqsmlid\(aq as the target lid for SA queries.
.SS Port Selection flags
.\" Define the common option -C
.
.sp
\fB\-C, \-\-Ca <ca_name>\fP    use the specified ca_name.
.\" Define the common option -P
.
.sp
\fB\-P, \-\-Port <ca_port>\fP    use the specified ca_port.
.\" Explanation of local port selection
.
.SS Local port Selection
.sp
Multiple port/Multiple CA support: when no IB device or port is specified
(see the "local umad parameters" below), the libibumad library
selects the port to use by the following criteria:
.INDENT 0.0
.INDENT 3.5
.INDENT 0.0
.IP 1. 3
the first port that is ACTIVE.
.IP 2. 3
if not found, the first port that is UP (physical link up).
.UNINDENT
.sp
If a port and/or CA name is specified, the libibumad library attempts
to fulfill the user request, and will fail if it is not possible.
.sp
For example:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
ibaddr                 # use the first port (criteria #1 above)
ibaddr \-C mthca1       # pick the best port from "mthca1" only.
ibaddr \-P 2            # use the second (active/up) port from the first available IB device.
ibaddr \-C mthca0 \-P 2  # use the specified port only.
